Viruses are obligate parasites which cause a range of severe plant diseases that affect farm
productivity around the world, resulting in immense annual losses of yield. Therefore, control …

Gene technology and plant breeding are combining to provide powerful means for modifying
the composition of oilseeds to improve their nutritional value and provide the functional …

Transgenes and endogenous genes are sensitive to silencing, in particular when the genes
are tandemly repeated. Their expression can be transcriptionally or post-transcriptionally …

Two transgenic callus lines of rice, stably expressing a β-glucuronidase (GUS) gene, were
supertransformed with a set of constructs designed to silence the resident GUS gene. An …

The major components of RNA silencing include both transitive and systemic small RNAs,
which are technically called secondary sRNAs. Double-stranded RNAs trigger systemic …

Post‐transcriptional gene‐silencing (PTGS) was first discovered in plants and results from
the sequence‐specific degradation of RNA. Degradation can be activated by introducing …

Virus diseases are among the key limiting factors that cause significant yield loss and
continuously threaten crop production. Resistant cultivars coupled with pesticide application …

Recent studies of gene silencing in plants have revealed two RNA-mediated epigenetic
processes, RNA-directed RNA degradation and RNA-directed DNA methylation. These …

Repeated DNA and cytosine methylation are common features of most eukaryotic genomes
and are frequently found associated with one another. Much repeated DNA, such as the …

The functions of two key, trichome-expressed genes were assessed using different
posttranscriptional gene silencing strategies (PTGS). Efficient RNA interference (RNAi) …
